摘要:
Power controllers, control methods and related integrated circuits for power supplies are disclosed. A power supply has a power switch and an inductive device. An exemplifying power controller comprises a first current source, a discharge time sensor, a representative current generator, and a pulse width modulator. The first current source generates a target current pouring to a compensation node. The discharge time sensor determines a discharge time of the inductive device. The representative current generator generates a representative current representing an inductor current of the inductive device. The pulse width modulator determines an output power of the power supply according to the compensation voltage at the compensation node. The representative current drains from the compensation node during the discharge time.

A method is presented for forming a transistor gate structure. A gate oxide layer is formed. Gate material is deposited on the gate oxide layer. A layer of silicon oxynitride is deposited on the gate material. The layer of silicon oxynitride, the gate material and the gate oxide layer are etched to form a gate structure. A silicon oxynitride region remains on top of the gate structure. A wet chemical process is performed to remove the silicon oxynitride region from the top of the gate structure. After performing the wet chemical process, spacers are formed around the gate structure.

A safety restraint for use with a towing assembly. The towing assembly is attached at a first end to a towing vehicle and at a second end to a towed vehicle. The restraint includes an elongate, hollow body that receives the towing assembly. The body is formed from at least two fibers that are woven into a multi-axis braid pattern. The cylindrical body at least partially encapsulates the towing assembly. For example, the body may include a first set of fibers arranged into a first ribbon of a particular width and a second set of fibers arranged into a second ribbon of a particular width, and the two ribbons are woven into a biaxial braid to provide the hollow body. The restraint also includes coupling mechanisms that retain the ends of the body and attach these ends to the towing vehicle and to the towed vehicle.

The present invention relates to compositions and methods for the use of SENP1 as a marker for cancer diagnosis, specifically prostate cancer. Still further, it relates to the use of inhibitors of SENP1 to inhibit cell proliferation of a neoplasm or tumor cell and to treat a hyperproliferative disease.

A tool-changing system for a press utilizes a rotary turret on which different tools are rigidly fixed. The turret includes a circular table base which is rotatably mounted on top of the press anvil. As the turret is turned, a different tool is moved into the work zone in vertical alignment with the upper tool on the press ram. The turret table can either be manually or motor driven in either direction between indexed operative positions. The indexing system which senses the position of the turret and indexes the turret to its next operating position uses only two simple sensors which are located beneath the turret table. Each sensor reads a different circular track on the underside of the turret table.

The present invention concerns methods of improving cardiac function in cardiac tissues of a recipient host by delivery of peripheral blood derived stem cells. The present invention also describes methods of stimulating cardiac tissue regeneration in a recipient host. Methods of treating a diseased cardiac tissue in a recipient host, as well as methods of obtaining a differentiated cardiac cell. Cardiac tissues subjected to these methods may be diseased or damaged, for example, by infarction, ischemia, chemotherapy, or infection. Peripheral blood derived stem cells used in the invention form new cardiomyocytes and also may form smooth muscle and endothelial cells.

A hand-writing input and recording device is housed in a case and may be hand-held by a user when in use. The device includes a contact element, an amplifying element, a sense element, an X-Y axes matrix element, a recording and storing element, a transmitting element and a receiving element. When the contact element generates a displacement variation in the X-Y axes, the X-Y axes displacement variation value will be emitted from the transmitting element to the receiving element and input into a computer for display on a computer screen to show the characters or patterns generated from the X-Y axes displacement variation value.

A non-riser valve assembly 30 includes a bonnet or housing 32, a bushing 34, a stem 36, a washer 38 and a stop 40. The assembly 30 further includes a coupling 42, a rotatable or movable disk 44, a fixed disk 46 and a bottom seal 48. In assembly, the bushing 34 and the stem 36 are located within an opening 50 of the housing 32 with the bushing being located between the housing and the stem. One of the stem 36 extends from one end of the opening 50 and the stop 40 is removably attached to the stem to limit the rotational movement of the stem within the housing. The coupling 42 is located in the opening 50 of the housing 32 and is in driving engagement with the opposite end of the stem 36. The movable disk 44 is located with the opening 50 and is coupled to the coupling 42 for rotation therewith. The fixed disk 46 is attached to the housing 32 within the opening 50 and is formed with a surface 224 which is in water-sealing engagement with a surface 162 of the movable disk 44. The disks 44 and 46 are formed with passages 164 and 218, respectively, the relative positioning of which is controlled by rotation of the stem 36 to control the flow of water therethrough.
摘要:
An apparatus for monitoring operation of a ratchet-based locking mechanism. The apparatus includes a ratchet and a pawl with a protrusion for engaging the ratchet during contact between the pawl and the ratchet teeth. The apparatus includes an elongated member or amplification arm extending from the pawl. The elongated member includes a base linked to the pawl and a tip spaced apart from the base. The elongated member is linked to the pawl to move when the pawl is displaced relative to the ratchet. The apparatus includes a sensor sensing displacement of the tip of the elongated member, which is greater than the pawl displacement, and the apparatus includes a processor monitoring displacement of the elongated member to indirectly monitor movement of the pawl protrusion during forward motion of the ratchet to verify the locking mechanism is working properly and the pawl will engage the ratchet to block reverse motion.
